EOS Bodies - For Stills / Re: Film EOS Body

I had an EOS 3 for several years and really liked it. Shot a large number of great pictures with that camera. Highly recommended.

Third Party Manufacturers / Re: To anyone waiting for a new 100-400L...

Just sold my 100-400.  I had it for almost 7 years and sold it for $160 less than I paid for it.  Pretty good return for the thousands of pics I shot with it.  Most of the shots were at the upper end of the zoom range, planning to buy a 400 2.8 later this year to replace it.

5D MK III Sample Images / Re: Aerial photos, balloons, planes, and others

Nice. Where'd you shoot those from? As far as I can remember, nobody is allow to get close to the practice ranges while they're actually using them.


Here is a link to the range I was at.  This is an old posting; however they are planning an open house this year in September. http://www.131bw.ang.af.mil/news/story.asp?id=123270422

I was there today as a Civilian DoD employee that was performing some work at the range.  I had a few minutes available before I left to snap a few pics.  You can't leave until the planes finish their runs as the road going out is right in line of the strafing pit!

Had not seen a topic with a subject such as this so I thought I would start one with a couple of images I snapped today.  These are two pics of a USAF A-10 "Warthog" as it was doing practice bombing and strafing runs on ground targets.  I only had a few minutes to snap shots (it was very cold and windy and I wasn't at all dressed for it) and I'm looking forward to going back at some point in the future to shoot some more.

"A built in clamp....... Minimal failure points.... How does it stack up?"

Pay attention Neuro, an engineer is talking about "minimal failure points."  That means this is BETTER than your combination of pieces loctited together creating multiple failure points that you believe is even stronger.

This kind of thing happens. Whether this particular one is real, I don't know. However, I do know it happens.  I'm an internal auditor in my day job and in my many years of auditing I've uncovered all sorts of fraud cases. The thing is, if someone is doing this at Dell or the shipper, they will eventually get caught. Greed is very powerful and it makes the crook steal more and more. I have worked with law enforcement to set traps in theft cases with hidden cameras to catch thieves that can't stop. Keep in mind, thieves don't think they are going to get caught or they wouldn't attempt it.

There was a scam very much like this a couple of years ago in my area at Best Buy.  Someone was buying items like stereo receivers, dvd players, speakers, etc. and returning them to the store where they were restocked on the shelves. The next person to buy them got them home and found boards and/or bricks in the box.

If you want a good "gym" lens, invest in a 135 f/2.  Not big and heavy, yet incredible in a gym on the 5d III.

More convenient yes, MORE secure, no.  I agree with C. Burch, you are adding another potential failure point, period.

So, a single threaded attachment that is frequently unscrewed and rescrewed and subjected to torsional stress during use is going to be more stable than a threaded attachment with threadlocking applied plus a clamping screw that's not subjected to unintentional torsional stress?  Sorry, no.  Yes, in theory, two connection points vs. one means two possible failure points rather than one.  If you were doing a 350' free rappel (I've done one), would you prefer to hang from a single loosely tied knot, or a pair of 8,000-lb-rated carabiners connected in series?  The latter has two possible failure points vs. just one - it must be less safe, right?

I can tell you that I spent over a year with the single lug connection, first as a FastenR-2 then FastenR-3 connected to a tripod socket, then with a FastenR-T1 connected through a Manfrotto RC2 plate.  I would frequently find the FastenR slightly loose - probably at least once per week.  It never loosened sufficiently for the camera to fall - but that's because I quickly got in the habit of checking the tightness of the lug several times a day.  In over a year with the FastenR-3 Loctite'd to a Kirk clamp attached to a body or lens plate, I have never had anything come even slightly loose.  I know which sounds more failure-prone to me, and I'm not a fan of letting untested theory outweigh empirical fact.

Sorry, I forgot that I was replying to the person that knows everything about everything.

Thanks.  So, basically, unless you loc-tite the BR nut to the QR clamp, you still run a risk of it unscrewing?

Not sure - if you slightly moisten the rubber compression washer and screw the lug in tight (with the solid aluminum, no risk of overtightening), probably not. But I see no reason to remove it routinely, so why not use Loctite? The Blue 242 type is semi-permanent - it's not going to come loose with normal use, but with a vice and a pair of pliers you can unscrew the lug.

Adding the Kirk1 clamp seems like a reasonable idea, but it just seems to be adding another point of possible failure.  I would think the BR screw in post with the rubber ring would stay tighter than a clamp.  Has no one ever had the clamp work its way loose?

I disagree.  With the Loctite, I wouldn't classify the lug-clamp connection as a failure point, so you're certainly not adding one. Moreover, if you frequently unscrew and reconnect the lug (which you'd do to attach to a tripod, for example), that makes the lug connection a much more likely failure point. There's no rotational stress on the clamp screw, so it won't come unscrewed unless you turn it. Orientation prevents unintentional turning - on a body plate, attach the clamp so the knob is under the lens, on a lens plate, attach it so the knob is away from your body. I've never had the clamps loosen even a smidgen.  So, overall, I'd say the BR lug attached to an AS-type clamp (the Kirk or RRS' new flat-bottom clamp) with Loctite, connected to AS-type body/lens plates, is both more convenient and more secure than directly attaching the lug to a tripod socket.

More convenient yes, MORE secure, no.  I agree with C. Burch, you are adding another potential failure point, period.

Canon General / Re: Photography magazines
« on: January 06, 2013, 10:01:17 PM »
Thanks all for the replies. I figured the magazines that I grabbed at the airport last week (outdoor photographer and shutter something) wouldn't be mentioned highly as they only had about 1-2 articles each that were of interest, it sounds like its more of the same elsewhere.

I buy a magazine or two from a newsstand periodically if I see something of interest in it.  Shutterbug is the magazine you were trying to think of I'll bet.  That thing is 95% advertising and is absolutely worthless. I've bought it before and won't make that mistake again!

The failures that I have read about relate to failure of the tripod socket itself on the camera body.  I have no idea how the tripod socket is attached inside the camera body?  It may vary by manufacturer and some may be more prone to failure than others.  I won't risk that. I have a BR strap; however, I only use it on a lens plate, never attached to the camera body.


That must have been a Sony :)  I've never heard that one. I suppose you could take it to the next level and start worrying about your lens mount...

I feel comfortable with the lens foot because it is a single piece of metal that has been threaded.  The tripod socket is actually inserted into the camera body and fastened there in some manner. So, it can come out of the body.

I did a 10 day float trip through the Grand Canyon 4 years ago which included over 120 rapids, several Class V.  All of my gear (and that of many others) was in Pelican cases.  The float guides and a pro photographer that was on the trip said that Pelican makes the best cases for this type of use.  I'm sure the guides especially know what they are talking about as they see plenty of different cases and bags and knows what works and what fails.  I use 3 different Pelican cases, depending on what size I need.
